Is it too late to stop global warming? We’re not sure, but this is not a drill. Our climate and our planet are too important for us to simply stand by as atmospheric warming poses ever-greater risks.

We need a carbon-free future sustained by clean and renewable energy from solar, wind and geothermal farms — not coal mines and oil wells — to fuel our cars, trucks, homes and businesses. So we enthusiastically embrace new ways to minimize and eliminate fossil fuel consumption.

​California is home to 12 percent of America’s population and the sixth largest economy on the planet, so reducing our greenhouse gas emissions is a big deal. California leads America in the attack on greenhouse gas. In 2002, our state set a goal of 331/3 percent renewable energy by 2020, subsequently increased to 50 percent by 2030. As we write, legislation is pending in Sacramento that seeks to increase renewable electricity usage even further across the state.
